The party itself is not a lot of work; actually it's fun.

What is a lot of work is all the pre-party clean up. Like cutting up the now two huge branches that fell off the maple, landing on the patio (and squashing more patio furniture) and the picnic table. Guess I'm making a picnic table tomorrow

And of course the driveway is "unacceptable" so across this week I'll be digging holes in the large pile of junk in the garage and shoving the engines, transmissions, and pile of other automotive junk into those holes

Stuff like that ;-)
